I have a build definition on visual studio online which creates an msi installation package using WiX.
How can I automatically deploy the msi package from VSO build agent to Azure VM after the build completes successfully?
Note: I prefer to use a post-build batch or powershell script as part of the build process. The script should copy the msi to the vm and install it.
You should use Release Management Online. It comes with VSO and allows you to easily orchestrate installing an MSI on any Azure server.

Microsoft just added RM in VSO and its simple to use. I setup an end to end web app deployment, buy as its just a PowerShell to do the install an MSI would be trivial. RM takes care of getting all of the bits to the right spot...

Honestly, it sounds hard, but is much easier than trying to do it all yourself.
